What’s the mean I’m really dumb and can’t do it x
1 answer:
Multiply the values across the rows. So you'll multiply each mark with its corresponding frequency
6*5 = 30
7*4 = 28
8*7 = 56
9*10 = 90
10*4 = 40
Then add up those results
30+28+56+90+40 = 244
Finally, you divide by 30 since this is the total number of scores (add up everything in the second column of the original table to get 30)
So we end up with the mean being 244/30 = 8.133 approximately
Round that value however you need to.

6-0
6 is the answer pls mark as brainliest
Cos9x - cos5x = -2sin2x.sin7x
sin17x - sin3x = 2sin7x.cos10x
so f(x) =
=
The answer would be 10 because if u put abcde over fghij, hi and cd are the same place so its the same answer or a mulitple of 10
Initial velocity (u) = 0m/s
Final velocity (v) = 20m/s
Time (t) = 10 s
Acceleration (a)
= (v - u)/t
= [(20m/s) - (0m/s)]/10s
= (20m/s)/10s
= (20m/s²)/10
=> 2m/s²
